Self-assembly of tungstophosphoric acid/acidified carbon nitride hybrids with enhanced visible-light-driven photocatalytic activity for the degradation of imidacloprid and acetamiprid

Insights into the Toxicity and Degradation Mechanisms of Imidacloprid Via Physicochemical and Microbial Approaches

“…The photocatalytic activity of HPW/ACN composites can be improved by improving the hole-electron separation efficiency. In another study, under visible light exposure (λ> 400 nm), the photocatalytic degradation rate constant of HPW/ACN was shown to be 16 times higher than that of ACN imidacloprid [89]. GO/Fe 3 O 4 /TiO 2 -NiO can be used as an appropriate photocatalyst for the degradation of organophosphorus pesticides in visible light.…”

Recent advances of semiconductor photocatalysis for water pollutant treatment: mechanisms, materials and applications

“…Soltani-Nezhad et al 142 synthesized a magnetic nanostructured composite photocatalyst (GO/Fe 3 O 4 / TiO 2 -NiO) with excellent photocatalytic activity to degrade 5 ppm of IMD under visible light. Sun et al 143 prepared a novel, efficient hybrid photocatalyst consisting of tungstophosphoric acid (HPW) and acidified carbon nitride (ACN). The HPW effectively trapped photogenerated electrons and provided a large number of adsorption and reactive sites.…”

“…By uniformly dispersing and anchoring Fe 0 on the surface of the black-TiO 2 , the material demonstrated a remarkable degradation activity and stability towards TC. This was attributed to the high dispersion of Fe 0 , which possessed a strong reducing 142 HPW/ACN (acidified carbon nitride), 143 Au-SnO 2 -CdS, 144 ZnO/CoFe 2 O 4 , 145 Cu@TiO 2 . 146 ].…”
